Configure the AD FS Servers in an Internal Load-Balanced Set in Windows Azure for Office365 Single Sign-On

Now that we have our two AD FS 3.0 servers setup in the same cloud service and installed into an AD FS farm configuration, we need to load balance them. Azure has a load balancer built into the product, we just have to configure it.

Add DNS Record

Now that we have our farm configured and the servers are load balanced, we need to ensure that the clients can get to them using the virtual IP of the Internal Load-Balanced Set.

In the steps above we created an Internal Load-Balanced set with the IP of 10.0.0.8. We now need to create an A record in the internal DNS, with a name of STS that points to the VIP. In my case sts.office365supportlab.com points at 10.0.0.8
